I completely agree with Damian´s report about the detrimental to
ecosystems, it is true that we are destroying our home; its¿ is devastating to
think how can someone do such bad to their home, we should be really
embarrassed. All earth has given us is a really beautiful place to live,
with everything we need, like food, oxygen, warmth, and so on.
The global warming has become a very big issue through the passing of
years. According to this graphic, temperature has had a big change since 1990,
and it continues getting worse.
Another problem this days, as Damian said, is the greenhouse effect
which is the phenomenon whereby the earth's atmosphere traps solar radiation, it
is caused by gasses in the atmosphere, such as carbon dioxide, water vapor, and
methane that allow incoming sunlight to pass through but absorb heat radiated
back from the earth's surface.
Moreover, another big deal going on is the extinction
of some animals; we kill hundreds of animals each day, and not only for food,
also for fashion; such as clothing or even furniture. Some of the animals in
danger of extinction are the giant otter and the nile crocodile; hunted or its
skin, the Iberian imperial eagle, which there are just 150 pairs left, the sea
turtle; chased by collectors and offered in luxury restaurants. These were some
of the hundreds of animals in danger of extinction. We have to stop killing too
many before they extinct and create a big problem to the food chain in the
world.
According to David´s blog the worst problem of the global warming is the
greenhouse effect, and it is true, it makes the climate a lot warmer than it
has to be. There are more problems though, such as deterioration in the ozone
layer, biodiversity loss, desertification, acid rain, and so on.
In my opinion the high-rise of temperature is a very important issue,
the global warming is not only affecting the temperature; it’s also affecting
the oceans (93%), the atmosphere (2.3%), the continents (2.1%), glaciers and
ice caps (0.9%), the artic sea ice (0.8%), the Greenland ice sheet (0.2%) and
the Antarctic ice sheet (0.2%). This is really bad because the poles are
melting and some beaches are disappearing, the animals that lived the poles
have to move to another type of ecosystem so that they can survive, whereas if
they stay they surely will die.
In addition, the UV rays are other problem; the ozone layer has been
deteriorating because of all the dangerous gasses in the atmosphere. Now it’s
really dangerous to be out under the sun without protection (sunscreen), it
will burn your skin and even you can get skin cancer.
